The features'of this invention are illustrated in the drawings applied to a web roll supply mechanism adapted for use. with printing machines. The web roll supply mechanism herein shown includes inits structure a high speedweb joining mechanism whereby the webs, of a replacement web roll and of an expiring web roll may be joined together without interfering with the operation of the machine. Referring to Figure 1, the mechanism illustrate'd isf adapted to support a plurality of web rolls-upon a shaft II, which is journaled at each ofits ends in standards or supports I2, an end view of one of which is shown in Figure 1.

The shaft II is a arranged to be rotated by suitable mechanism (not shown) to position the respective web rolls in desired positions.

A web roll supporting reel I3 comprising a pair I I3 is provided-with three radiallyextending arms I4, I5-and I 6 equally spacedapart peripherally about its hub portion II. An expiring web roll between the opposing arms ,Il thereof, a replacement web roll I9 between the arms I5, and a spare web'roll 2I between-the arms I6. The vari- 2 roll l9 to bring it up to the speed of the web 25 before its web is joined thereto.

Suitable web joining mechanism is provided for deflecting the running web 25 of the expiring web roll l8 against the web of the replacement roll i9, to press it against a previously prepared adhesive covered area upon the end of the web of roll I9, and for severing the expiring web 25 after a join is made. The means for deflecting the web 25 may be in the form of a brush,26 mounted on a bar 21 secured to arms 28, pivoted at 29, to an extension 3|, of a bracket 32, which is secured to a convenient machine part. One of the arms 28 is releasably connected to'one of another pair of arms 33 between which is supported a holder 34, in which a retractable web severing knife may be mounted. "A spring 35 is provided and connected to an arm 33 to act upon the connected arms to maintain them in web engaging position, as shown. A-cable 36 is provided and connected to the arm 28 to swing the brush 26 against the web to deflect the same into contact with the web end on the roll l9. The

arms 28 and 33, when not in use, may be swung out of the way into a position as shown in dotted lines in Figure 1.

The cable 36 is connected to an arm 31, swingable witha lever 38 mounted to a bracket 39 and the solenoid 42. I comprises a conductor 4| leading from amain power cable 48 to a terminal of the switch 46,, a conductor 49 leading from the other terminal secured to a convenient machine frame part.

The lever 38, in its swinging movement, is adapted through the cable 36 to pull the arm 28 to deflect the web 25, as above described. Means is It is necessary that the web deflector or brush '26 be held by the catch-44 against web deflecting operation by the lever 38, until the adhesive covered area of the web end on the roll I9 is in proper position relatively tothe brush for such operation. This is accomplished herein by the timing mechanism of this invention. A circuit closing switch 46 is mounted upon a stationary support or standard l2 and is electrically connected into the circuit containing the switch 4| Herein, the electrical circuit thereof to a terminal of the solenoid 42; From the other terminal of. the solenoid 42 a'conductor 5| leads to a terminal of the switch u, from the other terminal of which a conductor 52 leads to the other main power cable 53.. I

The switch 46 is herein shown in Figures 1-4 inclusive, adapted to be actuated by a system of cams and levers mounted on each of the arms i4, i5 and I5, each system being controlled by a cam 54, mounted to rotate with the respective roll on each arm, and positioned relative to the web end thereof, to controlthe actuation of the switch 48 in the desired manner above referred to. Each of the cams 54 is provided with a cam surface 55. The switch 46 is provided with an operating lever' 56 having a roller 51 upon its outer end which is disposed inthe path of, and for actuation by a camming finger 58, one finger being provided in I association with'each of the arms l4, l5 and I5.

.The camming fingers 58 are each secured to a,

rotatable rod or shaft 59, to which is secured a lever 'arm 6|, the free end of which is connected by a link bar 52, to a lever arm 63, of a bell crank 84, pivoted at 65, to the respective reel arm l4, l5 or l8. The other arm 66 of the bell crank 84 is provided with a roller 61, adapted to engage thesurface of the cam 54 and be actuated by the cam surface 55 thereof to swing the bell crank 64 and, through the bar 62, and the lever arm 6| to rock the rod 59 and swing the finger 58 into position to actuate the switch 46. A spring 68 is pro vided to act upon the bell crank 64 to maintain the roller 61 in contact with thesurface of the cam 54. By provision of the' above described mechanism the switch 46 maybe actuated by whichever cam 54 is with its supporting roll, and reel arm, in the web Joining position as shown in respect to the roll l9, but when in either of the other positions, as shown in respect to the rolls |8 and 2|, the'camming fingers 58 are not in position to eifectthe actuation of ,the switch 46.

Provision is herein made to adapt the timing mechanism for use whenweb rolls, other than of f full length, are mounted on the reel l3, and to permit axial adjustment of they reel. The rods or shafts 59 are secured at one end thereof tothe camming fingers 58 and are extended through the lever arms 6|, while being connected thereto for rocking movement thereby. The lever arms 6| are each secured against axial movement relatively to the reel i3 by being retained between the arms of a bifurcated bracket 69, secured to the inner face H of the hub I! of the reel l3.

The rods 59 are extended beyond the arms 6| along reel shaft H and are supported at their remote ends by passing through and being axially slidable in a collar 12, which is secured to the shaft u. I I The camming fingers 58 with the rods. 59 are maintained against axial movement by the flngers 58being disposed between-the flange of a sleeve-like bracket 13, and a collar 14 which is I supported upon the sleeve bracket 13 for rotation thereon with the shaft II and rods 59, the rods 59 passing through openings adjacent the periphery of the'collar l4. The collar is secured against axial movement in respect to the sleeve 13 by means of a plate 15 secured to the end face of the sleeve 13, which sleeve is secured to the standard l2.

Due to the above described structure, the rods or shafts 58 and the camming fingers 58 rotate with'the shaft I I, but are secured against axial-- movement therewith, while permitting axial movement of the shaft H to align the webs of the respective rolls with'the machine parts. operating thereon-and to permit the use of other than full length rolls without interfering with the operation of the timing device in its control of the web joining mechanism. v

In the form of timing mechanism illustrated in Figures 5 and 6, the switch 45 is mounted upon a flange 8| of a sleeve 82, which is supported upon the shaft The sleeve 82 is retained against rotativamovem'ent with thfshaft I by the action of gravity on a weight 83, secured to the sleeve by a rod 84. The sleeve 82-is secured to the reel l8 for movement therewith along the shaft by'a member 85 secured to the hub I! of the reel l3 and'fihich has a portion 86 thereof disposed ina groove 81 extending peripherally about the sleeve 82. The switch'46 is so mounted that it will remain constantly in stationary position in respect to the rotative movement of the reel l3 and of the web rolls l8, l9 and 2| and v 2,140,529 to properly position its operating rolleril into the path of slidable switch actuating members 00,

one of which ismounted upon the hub II of the reel I3 adjacent the base of each arm I4, I5 and I6 thereof. g

The switch actuating members 88 areeach provided with a stem 89, which extends along the hub II of the reel I3, being supported by a bracket 9i secured to the hub and by passing through an opening in the respective arm. A collar 92 is secured to each stem 09 to act as an abutment for a spring 93, positioned about the stem in abutment with the bracket III, to constantly urge the-member 88 out of switch actuating position. In engagement with the collar 92 isan arm 94 of a bell crank 95, pivoted to a bracket 06, which is secured to the respectivereel arm. The other opening in the reel arm and is connected to an 7 slidable member 88, the spring 93 acting to con into the circuit of the solenoid 42 through flexible arm 91 of this bell crank extends through an arm of another bell crank 99 by a link IOIf The bellcr-ank 09 is pivoted at. I02 to the respectivereel arm and is provided with an arm I03 having a roller I04 thereon, in engagement with the surface of the cam 54 for operation,

by the cam surface 55 thereof, to' actuate theswitch. 46 through the instrumentality of the stantly maintain the roller I04 in contact with the cam 54. n g

The switch 46 may be electrically connected conductors I05 and I06 and a connector block I01 mounted on the reel support or standard I2. The form shown'in Figures '7 and 8 difiers from that shown in Figure 5'in that the sleeve 82 is retained against rotative movement with the shaft II by a bar III extending downwardly therefrom into engagement with a rod IIZ-secured J by brackets H3 and H4 to the floor, or to a v. base member II5 of the-machine. In'this form,

the arm 91 of thebell crank 95 is connected to one end of a bar IIS slidably mountedtothe tained in contact with'the cam 54 by action of respective reel arm in brackets III and H8.

.The slidable bar H6 at its other end is connected toa holder III! onwhich is mounted a roller I 2| The roller I2I by being constantly mainthe spring 93, is effected by the cam surface 55,

to act through the bar H6 and bell crank 95, no

to move the member 88 into position to actuate the'switch 46 by the lever56 through roller 51.-

.By the use'of the timing mechanism shown in Figures 5-8 inclusive web rolls of other than full length may be employed and axial adjustments of the reel may be made without effecting the efllcient operation of the timing mechanism. In" all of the above forms the controlling'switch is mounted to be in a stationary position in respect to the rotation of'either the reel or. the web rolls,

thus eliminating the necessity of moving electrical contacts and devices with .their'attendant disadvantages. v w I .It will be understood that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present' embodiment be consideredin all respects as "illustrative and not restrictive, audit will be further understood that each and every novel feature and combination present in or possessed by the mechanism herein disclosed forms a 'part I of the invention included in this application.
